🩺 Early Pregnancy Scan – Complete Guide
Pregnancy brings both excitement and curiosity. The very first ultrasound, known as an Early Pregnancy Scan (or Dating Scan), plays a key role in understanding your baby’s development in the initial weeks.
This scan usually happens in the first trimester — between 6 to 12 weeks of pregnancy — and provides the earliest look into how your baby is growing inside the womb.
At Nisarga Diagnostics, Sanjaynagar, Bengaluru, our fetal medicine experts guide every mother through this crucial phase with care, accuracy, and compassion.

💡 What Is an Early Pregnancy Scan?
The early pregnancy scan is a type of ultrasound performed to confirm pregnancy, measure how many weeks pregnant you are, and assess your baby’s health.
This scan helps determine:
- Whether the pregnancy is developing inside the uterus (not ectopic).
- If there is one baby or twins.
- The baby’s heartbeat and growth.
- The expected due date (EDD).
It’s often called a dating scan because it helps calculate the gestational age of your baby more precisely than calendar counting or the last menstrual period (LMP) method.
📆 When Should You Do an Early Pregnancy Scan?
Most specialists recommend doing your early scan between 6 and 10 weeks of pregnancy.
- At 5–6 weeks, the gestational sac and yolk sac can be seen.
- At 6–7 weeks, the fetal pole and heartbeat are often visible.
- By 8–12 weeks, the baby’s head, body, and limb buds become clearer.
Doctors usually prefer performing the scan after 6 weeks, as it’s the best time to see the baby’s heartbeat clearly.
If you do the scan too early (before 6 weeks), the baby might not yet be visible, leading to unnecessary worry.
🩸 Why the Early Pregnancy Scan Is So Important?
This scan gives valuable insights during the early phase when your baby is most delicate.
Here’s why it’s so crucial:
- Confirms Pregnancy Viability
The scan checks if the embryo is growing normally and if there’s a visible heartbeat. A steady heartbeat confirms a healthy start.
- Detects Ectopic Pregnancy
Sometimes, the embryo implants outside the uterus (commonly in the fallopian tube). Early detection through ultrasound can prevent complications.
- Detects Multiple Pregnancies
If you’re carrying twins or triplets, the early scan will identify it, helping your doctor plan nutritional and medical care accordingly.
- Helps Estimate Accurate Due Date (EDD)
The Crown-Rump Length (CRL) measurement is the most accurate way to estimate the expected date of delivery.
- Identifies Abnormalities Early
Although it’s too soon to detect detailed anomalies, doctors can still see early warning signs such as a missing heartbeat or irregular sac growth.
🩺 What Happens During the Scan?
- You will be asked to lie on the examination table.
- A gel is applied on your lower abdomen to help sound waves pass efficiently.
- The sonographer moves the transducer probe across your tummy to capture images.
- In some early cases, a transvaginal scan may be recommended for clearer visibility.
The process is painless and safe — there’s no radiation involved, and the sound waves used in ultrasound do not harm the baby or mother.
You will see your baby’s tiny heartbeat flickering on the monitor — one of the most emotional moments for every parent! 💓
🧠 What the Doctor Observes
During the early pregnancy scan, the doctor carefully studies:
Parameter | Purpose |
Gestational Sac | Confirms intra-uterine pregnancy |
Yolk Sac | Early nutrition source for the baby |
Fetal Pole | Visible structure of the embryo |
Heartbeat | Confirms baby’s viability |
CRL (Crown-Rump Length) | Measures baby’s growth and estimates due date |
Amniotic Fluid | Indicates healthy surroundings |
Uterus & Ovaries | Detects any cysts or fibroids |
These details create a complete medical picture of how your pregnancy is progressing.
💬 How to Prepare for the Scan
Preparation is simple:
- Drink some water before the scan (a slightly full bladder helps clearer imaging).
- Avoid applying creams or lotions on your abdomen before the scan.
- Wear comfortable clothing for easy access.
- Carry previous reports or blood test results if you have them.
- Relax — it’s completely safe and routine.
What You Might See During the Scan?
You may notice the baby’s head and body outline, sometimes even tiny limb buds depending on your gestation. The image will appear in black and white, because ultrasound beams use sound waves, not light — meaning color details cannot be captured.
If the doctor notices any concern (like delayed growth or missing heartbeat), they may advise a follow-up scan after a week for reassessment.
